SNOW-PLOW,

SPECIFICATIONAforI'ning partof Letters Patent No. 629,917, dated August 1, r.1899.

Application iiled September 16, 189.8. Serial No. 691,109. (No model.)

lowing is a specication,'reference being had' therein to theaccompanying drawings. This invention relates to snow-plows, and particularly to a Vcoiistruction which can be used as a plow or as a surface-roughener in connection withthe plow.

The invention has for its object to provide a construction by which the plow is supported upon suitable .carriages and can be elevated or depressed as desired and to a construction by which the angle of draft can be varied to present the plow at the proper inclination for different character of material to be removed'.

It has as a further object to provide a particular construction of knife and of blades Other objects and advantages 'of the inven- I tion will hereinafter appear in the following description and the Anovelfeatures thereof particularly pointed out in the appended claims. 1

In the drawings, Figurel is a side eleva- Fig. 2 is a similar view from the opposite or angle face. Fig. 3 is a top plan. roughening-blade, and Fig. 5 is a vertical section of the same.

Like numerals of-reference indicate like parts throughout the several figures of the drawings.

The sides 1 of the plowproper are connected together in an an-gularform'fso as to present one surface at substantially an angle of forty-five degrees to the other. These sides are provided with suitable cross-pieces or stiieners', 4, and 5, upon whichthe top 2 is applied. braced by tie-rods 6, which are provided with buckles 7, engaging the reverse threads upon the rods and bymeans of Whichthe rods can be properly tightenedj Theupper surface of the top 2 is Vprovided with a bearing-board Fig. 4 is a detail elevation of the The sides areralso suitably Sand the kstraight, side 9 of the plow with a steel blade 9, which extends slightly below the surface of the side to insure a positive hold against lateral movement of the plow and to afford a proper scrapingfsurface. The angle side is likewise providedwith a blade 10 of particular construction, as shown in Fig. 4, and having a series of teeth 10a bent at an angle to the lblade and in the direction of :draft'of the plow., These blades 10 extend slightlybelow the bottom of the side andare secured vby suitable bolts passing through elongated apertures in the blade, by which the vertical adjustment of the blade is permitted. The blade may be omitted if it is not desired to roughen the surface scraped, and any suitable scraperblade may be applied in its place or the edge of the side used for the scraping action. The slots are so located as to permit the 'upward movement of the blade abovethe bottom ofA the side, and thus remove the same from action when desired. The, angle side of the plowV isl provided with `suitable socket plates 11 for the reception of drop-pins cai` ried by the side ,wingj 12. This wing is intended for use in removing deep snow or s now which accumulates at theouter portion of the side. The noseof the plow is also suitably shod with metal, as at 13, and provided with a 4strap -14 for the -attachment of .a vdrafti loop ,17 extends a supporting-beam18,which at its opposite ends is supported upon Aand carried by suitable carriages-for instance, sleds, as illustrated. The guide-blocks 16 limit the lateral movement of the plow upon this beam, and the loop 17 limits its vertical 95 movement while allowing asuitable play of the plowin passiugover obstructions.- -The beam 1S has p-ivoted thereto a lever-19 in any suitable manner--for instance, by means of the loop 2G and .blade 21, as shown-the said 10o bolt passing through the beam and lever, while the loop provides a support and bracing connection therefor. Extending downward from this lever is a rod or link 22, having an eye atits lower portion, adapted to engage a hook 23, secured to the cross-piece 4 of the body of the plow.` The lower end of the lever 19 bears upon asuitable wear-plate carried by the bearing-board 8, so that when the leveris thrown forward the plow is forced downward and when the leveris thrown backward the plow will be elevated through the connection therewith.

The rear end of the beam 18 is secured to the carriage or sled by means of the loop or strap 24, bolted to the sled, while the front end of the beam is provided upon its under surface with a plate 25, which cooperates with a gear-plate 26, extending at right angles thereto and provided with a series of adjusting-apertures, as illustrated. The opposite end of the plate 26 is provided with a draft-rod extending to and connecting with the strap l5, carried by the inclined face of the plow. It will be seen that the king-bolt which passes through the beam 18 and front sled may be removed and placed in another adjusting-aperture upon the plate 26 when it is desired to alter the inclination of the angle-face of the plow relative to the front sled. It is desirable to regulate this inclination for different classes of work and different character of material to be removed, as the` draft required can best be applied when the angleface of the plow is presented at the proper inclination for any particular character of workfor instance, removing wet or dry snow. This adjust-ment of the plow is permitted by means ot' the flexible chain connections .between the front and rear carriages or sleds. The rear sled is provided with suitable runners 28, which are stiffened by braceblocks 29 and yieldingly connected with the plow by means of chains 30. At the point of connection with the plow the runners of the rear sled are located within cut-away portions of the plow-body. The front sled is provided with similar runners 3l, connected by a crosspiece 32, having thereon a bearing-block 33, upon which the gear-plate 26 rests and through which the king-bolt 34 passes. These runners are provided at one end with straps 35, through which al pivoting-bolt 39 passes and upon which bolt the usual pole-roller 36 and strap 37 are carried. The pole 38 has been broken away; but it is obvious it may be of any desired character.

From the foregoing description the operation of this invention will be apparent, and the plow can be lowered into operation or raised therefrom by the manipulation of the lever 19, while the inclination of the angleface of the plow can be varied by an adj ustment of the gear-plate 26 and the draft of the plow correspondingly altered. By the arrangement of bolts and blade-knife the ,plow may be used as a surface-roughener and the thrust from the angle-face of the plow resisted.

It is obvious that changes maybe made in the details of construction and coniiguration without departing from the spirit of this invention as defined by the appended claims.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In a snow-plow, the combination with carriages, of a beam supported thereby, a plow mounted loosely upon said beam for vertical and angular movement independently of said beam, means supported upon the beam for sustaining the plow in. an elevated position, and a draft device for maintaining the angular adjusted relation of said plow to said beam; substantially as specified.
